Such a. device is the various advantages resu ting from their shown in Figs. 1, 2, and 3.

This universal invention. Fig. 5 is a side or edge elevation of the devices shown in Fig. A. Fig. 6 illustrutes a single feature of my invention in side edge view. Fig. 7 is a front elevation of the mechanism shown in Fig. 6.

A indicates a tube for conveyin a fluid or fluids forward to the nozzle B. 'l iese lluids may be impelled forward through the tube A by any suitable means. Some of the wall own menu for this purpose are a rubber bulb, such as W, or a pump with or without a valve, all of whose operations are well understood device of more limited scope, but e1:- ceedingiy useful within limits, is the one shown in Fig. 5 where the aim between the nozzle B and t section is shown at C. This joint is located behind the mirror. -It enables the front end of the nozzk to be turned around anywhere in the circular-dine Y, and thus adapts the nozzle to be used at many convenient points in connection with the mirror. Where the device is to be used osesprayer, the delivery-tube will be divided into two parts, one for conveying the it: end the other for conveying a liquid. the mode.
